used to measure the amount of irrigation applied. Meter accuracy

was checked with standard volumetric containers. Via-flow (a white

porous plastic) drip tubing was used in treatments ADI and MDI.

Sprinkler irrigated (SI) plots had dykes constructed between rows

to prevent runoff from the four small radius sprinklers in each

plot.

 One-thousand lbs/acre of a 3-14-4 mixture was incorporated

into plant beds of all treatments to supply 30 lbs/acre N, 60

lbs/acre P, and 30 lbs/acre K (N = nitrogen, P = phosphorus, and K

= potassium). A 19-0-24 mixture (1100 lbs/acre) was applied to

supply 200 lbs/acre N and 200 lbs/acre K. The 19-0-24 was applied

in bands six inches from the plant row on each side of the bed to

treatment SI. One band of 19-0-24 was applied to treatment ADI

between the drip tube and plants to evaluate the influence of high

fertilizer salt concentration on tomato yield. In treatment MDI,

the 19-0-24 was dissolved in water, filtered and injected into the

drip tubing at weekly intervals to supply 20% of the total during

the first seven weeks of growth and the remainder between 8 and 13

weeks.

 Tomatoes were hand-harvested at two or three day intervals, a

total of ten times. Yield is reported in tons/acre of pink and

mature green fruit of marketable sizes.

 Experiment #2: Tomato plants of the Sunny cultivar were

transplanted in field plots on 8 April in a year with higher

rainfall than for experiment #1. Soil type was Orangeburg loamy

fine sand (fine, loamy, siliceous, thermic, Typic Kandiudults).
